Abstract

Uranium isotopes in environmental samples play a critical role in various scientific and industrial applications, including nuclear power generation, radioactive waste management and disposal, geological studies, and environmental monitoring. Accurate and reliable determination of uranium concentrations is essential for ensuring environmental safety, regulatory compliance, and advancing research in these fields. In this study, a method utilizing recycled UTEVA resin columns for uranium separation and quantification was developed and evaluated at the Central Laboratory for Environmental Radioactivity Measurements Inter-comparison and Training (CLERMIT). The primary objective was to assess the feasibility of reusing UTEVA resin columns for uranium isotope separation while maintaining high analytical performance. The method was tested using Certified Reference Materials (CRMs) with different matrices and varying activity concentrations of 238U and 234U to ensure its robustness and reliability across diverse sample compositions.The experimental findings demonstrated that the recycled UTEVA columns effectively retained their separation efficiency, yielding highly accurate and precise uranium measurements. The results indicated that the relative error and relative standard deviation for uranium isotope separations ranged from 2.34% to 5.92% and 6.10% to 6.21%, respectively. These findings confirm that the method is not only viable but also highly efficient in terms of precision and accuracy. The successful implementation of recycled UTEVA resin columns offers a cost-effective and environmentally sustainable approach to uranium isotope analysis, contributing to advancements in nuclear and environmental sciences.
